Perioperative Identification of an Accessory Fissure of the Right Lung

Figure 3

CT scan. (a)-(b) Coronal sections showing the bifurcation of the bronchus to the apical segment and the basal segments. There is no evidence of accessory branching, so no morphological extra lobe; hence there is only an accessory fissure (arrows). CT scans (a) and (b) have respiratory artifacts as seen at the level of the diaphragm. (c)-(d) Transversal sections showing the superior accessory fissure of the lower lobe of the right lung.
